WWF's mission is the conservation of nature. Using the best available scientific knowledge and advancing that knowledge where we can, we work to preserve the diversity and abundance of life on Earth and the health of ecological systems by protecting natural areas and wild populations of plants and animals, including endangered species; promoting sustainable approaches to the use of renewable natural resources; and promoting more efficient use of resources and energy and the maximum reduction of pollution. We are committed to reversing the degradation of our planet's natural environment and to building a future in which human needs are met in harmony with nature. We recognize the critical relevance of human numbers, poverty and consumption patterns to meeting these goals.

Helping People Help Animals

PHS/SPCA is a private, independent, non-profit, and our scope of services goes beyond that of a so-called no-kill, or limited admission, facility. As an open-door shelter, PHS/SPCA accepts all animals brought to us, regardless of age, breed or size, and we’ve rehomed 100% of the healthy dogs and cats in our care since 2003 and promise to do this going forward. While rewarding, this isn’t our most challenging work and doesn’t define us. We accept our community’s sick, injured, abused, unwanted, stray, neglected and older animals; donations to our Hope Program enable us to help and rehome approximately 200 every month. (Sadly, private shelters in many communities never give them a chance). We rehabilitate wildlife, make spay/neuter free for our low or fixed-income residents, educate children, and investigate animal cruelty. PHS/SPCA is one of the few shelters in the entire state accredited by the American Animal Hospital association and we’re a gold-level GuideStar Exchange participant (click the seal below to access our GuideStar nonprofit report). We take our work and mission seriously, but also have fun. It's why we've adopted "Sit Happens!" as our Behavior & Training Dept slogan and have "Go Nuts” emblazoned across the back our of mobile spay/neuter clinic. Most important, we’ve earned our community’s trust, involvement and support.

The mission of Operation Kindness is to care for homeless cats and dogs in a no-kill environment until each is adopted into responsible homes and to advocate humane values and behavior.
